To @ZZ wil/m it may concern.'

l Beit known that I, NioKoLAs SPUnerN, a citizenpfthe United States, and a resident oi Ottawa, in the county of Lasalle and State of illinois, have invented a new and Improved Pulverizer, of which the following is a full, clear, and exact description'.

My invention relates to certain rimprovements in pulverizing machinery Which are capable of general use in machinery of that character, but are especially adapted for use in disintegrating cla-y and similar substances.

The principalobjects of the invention are to provide means whereby the material upon entering` the machine can beacted upon by a stronger force than that applied after the material is partially pulverined and to provide ineens :tor adjusting the walls oit the pulverizer-charnber `in such `a manner as to take up weer and yet furnish ay substantially circular interior at all times. i accomplish the first object by certain improvements in the inanner'of supporting and manipulating the pulveri-zing-hammers and the second by certain improvements in the construction ci the casing itself. y Further objects of the invention will appear below. f'

Reference is to be had to the accompanying drawings, forming a part of tbisspecilication, in which similar characters of reference indicate corresponding parts in all the hgures.`

Figure 1 is an end elevation of a pulverizer, showing one forni of my improvements, parts being broken away to show interior construction in section. Fig. 2 is a sectional view on the line 2 2 of Fig. 1. Fig. 3 is a plan of a portion of the device employed to support the ulverizing-hammers, end Fig. 4 is a sectiona view on the line -1 el of Fig. 1.

i have shown an external casingll), suitably supported bya frame 11 and adapted to inclose an interior casing composed of a plurality of parts adjustably mounted With respect to each other. This interior casing comprises a bottom section 11a, mounted on a movable frame 12, which is provided with screws 13, operating in bearings 14' and each having abend-wheel 15, by means of which the bottom section is adapted to be raised and lowered. Adjacent to the bottom secn tion and fitting the ends thereof isa second section 16 on each side. This section is'piy- .other at their upper ends by the/screws 19.

, y, M K otally mounted with respectto the bottoni. section and is provided withan ear 1?-, kto which link 18 is iv'otally connected. y This link is connectedp 'with a bolt 19, passing through the frame 11 and adjustable with respect thereto. The upperv end ci the section lisprovided with a beveled surface 20, Which 'engages a correspondingly-beveled plate' 21,'mounted on the frame 11. The plate 21 is adaptedto su port a sliding iframe 22, carrying a Wearing-p ate 23, composed of 6 hard duralle material. v The frame .J2 is connected lwith a bolt 24, Which .is adjustably connected with the frame 11, wherebyv the wearing-plate 23 can be adjusted toward and from the center of the inachine. y Above the :trame 22 is a plate 25, similar to the plate 21, but in reverse position.l A section 26 is mountedabove the plate 25 and is provided with an ear 27, ccnneotedwith a link 28 and bolt `and with a beveled surface 30, similar to the corresponding features of the section 16. This section is provided with a lining 3i 'in theforrn of e. series of plates constructed ci' hard and durable material and rorided with a roughened surface or series o corrugations upon their interior. These Iplates are each provided with a projection 32, extending through the section 26. These projections are provided With perforations 33, through which passes a rod 34, held in position by Wedges 35, as shown in Fig. 4. The sections 26 on the two sides of the casing closely approachv each and are supported by a bracket 36, which has projections' 3? entering depressions 38 in the ends or' the sections. This bracket is connected with a fair oi screws 39, having 'feet 40, which e hand-screws 41, mounted in lugs en the cesing 11 to provide for adjustment,

The parts of the device so liar described n are constructed in this manner for the pu:-

pose of affording en adjustmentfof the interior diameter' oli the casinglvwithout materially changing the shape of the saine.r vWhen it is desired to decrease the interior diameter, .the section- 11 is raised by the screws 13, While the sections .1 6 on'each side are lpermitted to move inwardly at theirnpper ends The beveled surfaces 20 slide up lthe lower inclined surfaces of the plates 21, and the sections 16 are therefore lorced radially toward the center. The

lil

frames 22 are moved inwardly a sufficient vdistance to cause the plates 23 to form a confor receiving material and a discharge-outlet y 43. I have also shown a hand-hole 44, through which the interior of the device can be re ached. 4

In bearings 45, supported by the frame 11 or in any other convenient manner, is mounted a shaft 46, to which power is applied for operating the machine. This shaft is pro vided with a spider 47, on which are -located a series of longitudinal bars 48. These bars are connected withthe spider by means of bolts 49, and?,spacing-pieces` are preferably provided between them and the spider,- so that by introducing spacing-'pieces of different thicknesses the location of the longitudinal bars dan be regulated with respect to the center of the shaft. On the longitudinal bars are located U-shaped brackets 51, the body of the bracket being secured to the bar. In the drawings I have'shown some of theseas integrally mounted on the bar and others as secured to it by rivets or the like. These brackets are provided with perforations through which rods 52 pass. I

'have shown two of thesel rods located the same distance from the center of the shaft and at a point between them, and nearer the shaft I have located a third rod 53. The

.third rod is designed for pivotally\ mounting the hammers which are to beemployed for pulverizing material. -I have shown these hammers mounted in two ways. At

the entrance end of the machine, where the' material is hard and has to be operated upon with considerable force, I have pivoted supports 54 directly on the bars 53, ard these Supports are located in such a position as to On the ends' pass between the two bars 52. ofthese supports are mounted the hammers 55. It will be obvious that these hammers are compelled to strike a blow commensurate with the speed of rotation ofthe shaft. They are adjustablyl mounted with respect to the supports by means of studs 56, passing throu rh slots 57 in the hammers. While these iammers are properly mounted for'the purpose of the preliminary' breaking ofthe material, it has been found'that after this preliminary operation is started the lumps which arenot to be passed through the machine, but are to be discharged from it in an unpulverized condition, should be handled with less force, and consequently I have provided a series of supports 58, which are inthe form of curved bars passing around the bars 53 and pivoted thereon. These supports are connected. with hammers 51?, located outside the two barsv 52 and adapted to engage with the one of them which is in advance of the support. On the other arm of the support 58 is a weight 60. This construction vpermits the rapid rotation of the shaft to throw the hammers up into operative position by centrifugal force, the forward side of the support resting against the rear bar 52; butI if any serious opposition is made the whole support, with its hammer and weight, will yield vin such a manner as to permit a hard lump to ass along the machine without being handled) as forcibly as it would be by the hammers 55.

By constructing a pulveriZing-machine in accordance with the principles set forth above, whether in the form. shown or not, the material is subjectedI to the full .force of the hammers 55 when it first enters the machine; but such lumps as are not broken up by this operation are passed through the machine and are handled in the further operation thereof in a more gentle manner, so that tended to be broken up at all can be passed ythey can be discharged without injury to the working parts, and those which are not inf on without interfering with the pulverizing of the softer materials..

Itwill be noticed that the hammers 59 are beveled upon their Working surfaces. This allows material to be forced between them and the coacting walls of the pulverizer in such a manner as to secure thenecessary amount of pressure to properly vwork the materials. Y Y

vHaving thus described my invention, I claim as new and desire to`secure by Letters Patent 1.
